IMPROVEMENT IN PACKAGES FOR PUTTING UP CAUSTIC ALKALIESI ACIDS. Sic.

Specification forming part of Letters Patent No. 128,176, dated June 18,1872.

' To all 'whom it may concern:

Beit known that I, JACOB H. SEIBERT, of the city and county ofPhiladelphia and State of Pennsylvania, have invented a new and usefulImprovement in Packages for Putting Up Caustic Alkalies, Acids, Salts,and similar articles, of which the following is a specification:

My invention relates to packages for putting up caustic alkalies, acids,salts, and similar articles which are corrosive or deliquescent in theirnature, and which require a case, carrier, integument, or receptaclethat will protect them from the eifects of dampness, fire, andatmospheric iniiuences; and it consists, iirst, in a carrier of taperingor other suitable form cast from a plastic material around a centralcore, and within an outer case or mold, so that the sides and bottom ofthe carrier are formed from one and the same material at one operation,uniform, and graduated in size, and without the use of an outerprotecting-wrapper;

said receptacle, carrier, or integument to be finally nished, ifdesired, by coating with a resinous, tarry, or asphaltic wash orcoating, or. with a wrapping of suitable paper, and in any of thewell-known ways 5 second, in a central core, around which the plasticmass is cast, provided with a base-ring, which determines the thicknessof the walls of the carrier, in combination with an outer shield ormold, which is made in two or more pieces,

andof form corresponding. to the core, said pieces being held in placeby a binding-ring or clamp, which devices, taken together, constitutethemold or device for forming the case, carrier, integument, orreceptacle; and third, in a condenser or congealer for molding andcooling or congealing the caustic alkali, salts, or other materialprevious to its introduction into the carrier or integument, saidcondenser being of form and size to correspond with the carrier, andcomposed of two or more parts, which are held together by a ring, clamp,or other suitable device, the removal of the ring or clamp allowing theparts forming the condenser to separate so as to facilitate the removalof the congealed mass.

Most if not all of the packages of caustic alkali and similar corrosivesubstances heretofore put upon the market have been inclosed meeting thewants of the manufacturer and user to a certain extent, in enabling thearticle to be stored and transported in packages of from one poimd up, so as to meet the wants of families and small dealers, are yet highlyobjectionable in many respects-first, for the reason that the action ofthe alkali upon the metal forms a rust, which injures the article itselfboth in color and quality; second, by reason of the difficulty withwhich the alkali is removed from the metallic case, oft-en necessitatingthe introduction of the can into water and the removal of theV alkali byboiling, in which case the iron-rust discolors the solution, and third,in the cost of the metallic case or carrier, which is so high as tomaterially lessen the prots of manufacture and increase the cost to theconsumer. My object is to produce a carrier, integument, or receptacledevoid of these objections at a cost less than one-fourth that of thepresent carrier, and one which fully meets the wants of the trade.

In the drawing, Figure 1 is a vertical central section of the mold, itsring or clamp, the core, and the intermediate ring lying between themold and the core, all being in their-relative positions as used'incasting the carrier; Fig. 2, a section similar to Fig. l, showing thecarrier cast and within the mold. Fig. 3 is a vertical central sectionofthe core, ring, and carrier, the outer mold or shield having beenremoved. Fig. 4 is a carrier removed from the mold. Fig. 5 is aperspective view of the condenser or congealer. Fig. 6 is a verticalcentral section of the condenser or congealer filled with causticalkali. Fig. 7 is a perspective view of the two parts of condenser orcongealer separated from and on either side of the block of alkali. Fig.8l is a vertical section of the completed package, showing the coveringor closing disk, &c.

Like letters refer tolike parts in the several figures.

A is the central core or former. It may be of any desired shape,provided, always, that it taper slightly from base to top. B is a co1-lar, ring, or surrounding frame, which will be of such breadth as isrequired to give the desired thickness of walls in the cast. C is theouter shield or mold, which corresponds in form and taper with the coreA. This mold is formed of two or more pieces, made to t closely at theirjoints, and held in position by a ring or'clamp, D. D is the ring orclamp, which, sliding down upon the taper of the mold C, wedges orclamps the pieces thereof firmly together. The mold may be made ofmetal, clay, or other suitable material, and according as the basethereof is square, oblong, or cylindrical, so will be the shape ofltheparts B and D. The projection or collar B may be cast upon the core A orupon the mold C, or itmay be a separate ring, as herein represented.

To construct a package the core A is placed upon a suitable bed or tablewith the collar B at its base, outside of which, and forming a closejoint therewith, are the several parts forming shield or mold, held inposition by ring D or its equivalent fastening, all occupying therelative positions shown in Fig. l. The plastic mass, which may be acement, plaster Paris, a composition of glycerine, wax, and paper pulp,or any of the Well-known compositions which set7 to form a firm cast, isthen introduced into the `mold in such quantities as to iill the sidesthereof and cover in the top ofthe core to the desired depth. As soon asthe mass has set the ring D is removed and the pieces forming mold Cfall apart, leaving the cast or carrier E upon the core A, as rep-`resented in Fig. 3. Upon removing the carrier from core A I have asimple cast like that shown in Fig. 4.' This cast may then be furtheriinished, if deemed desirable, by coating it with a wash or coating ofresinous, tarry, or asphaltic matter, sealing-wax, &c., or it may have awrapper of paper or other fabric attached to it in any of the Well-knownways. This completes the carrier, which is formed, by means ofthe mold,without either an inner lining or an outer wrapper of paper or otherfabric.

F F, Fig. 5, represent the halves of the condenser or congealer, whichare held together by the ring or an equivalent fastening device. Thecondenser or congealer may be made of cast-iron or other suitablemateria-1. I have here represented it as made in two parts, but it canbe made in as many parts as may suit the convenience of the user,provided the united parts t accurately and form a mold corresponding insize and shape to the carrier which is used.V The parts forming thecondenser are held by the clamp or ring G, which, sliding down upon thetaper of the condenser, wedges the several parts together. Thecondenser, while in the position shown in Fig. 5, is filled with hotcaustic alkali or other material, which is allowed to congeal orsolidify therein. When it is desired to remove the block of alkali fromthe condenser a slight tap upon ring G loosens it, causing it to fallolf, so that the pieces forming the condenser may be separated, as shownin Fig. 7 of the accompanying drawing. To complete the package thecarrier, formed as hereinbefore described and shown in Fig. 4, isinserted and placed over the block of caustic alkali H, Fig. 7. Upontilting up the carrier the block of alkali Will fit snugly and retainits place therein. The disk I, Fig. 8, which can be of the the samematerial as the rest of the carrier, or of other suitable material, isthen placed in the top of the package, resting upon the alkali, andhermetically sealed with clay, sealing-Wax, resin, or any suitablematerial for forming a lid and air-tight integument. This completes thepackage, which will correspond in crosssection, to Fig. 8 of thedrawing.

Having thus described my invention, I claiml. The package, carrier, orintegument for caustic alkalis, acids, salts, and other chemicals, castfrom plastic materials at one operation, and coated with a resinous orother protecting coating, as herein described.

2. The mold for forming a package or carrier, consisting of core A, ringB, shield or mold C, and clamp or other suitable device D, as herein setforth.

3. A condenser or congealer for congealing or solidifying, for thepurpose of transferring into any other carrier, caustic alkali, salts,or other chemicals, composed of two or more parts held together by aring, clamp, or other suitable device, substantially as described.

In testimony that I claim the foregoing I have hereunto signed my namethis 29th day of May, 1872.

JACOB II. SEIBERT.
